IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Leters Patent No. 157,121, dated November24, 1874; application filed July 10, 1874.

T0 all whom 31% may concem:

Be it known that I, JOHN VVHEELER EL- LIOT, of the city of Toronto,Province of Ontario, Canada, have inventednew and nsefnl Improvements inHeating-Stoves, of which the following is a specification:

Inventors and manufactnrers have been for years and still areendeavoring to produce a cheap stove which Will extract the whole heatfrom.the fuel and convey it to the atmosphere with the least possiblewaste. Base-bnrncrs innnmerable have been designed With this 0l)- ject,and althongh some have proved so far snccessfifl, they all have oneserions fault, viz., complication et parts, and, consequently,expensiveness in their construction. Bich men can, it is true, obtain astove which Will, in time, save in fuel its great cost, but to the poorman this advantage is practically denied, as he is nnable t0 pnrchase soexpensive an article. The object of my invention is to prodnce a stovepossessing the main advantages of the expensive article, but so simplyand cheaply constrncted that the poorest may secnre it. My inventionrelates, first, to an improvement in the manner of conveying, around thebase of the stove, the smoke and heated air, and extracting therefromall the calorie before permitting it to escape; and, secondly, in animprovement in the manner of adjusting or affixing the mica paper orlights around the body of the stove. The first part of my inventionconsists in having a three-way draft passage on the smoke-vent of thestove, With radiating-pipe proceeding from each branch. The pipe comingfrom one of the holes, at right angles to the stovc, is bent downward,and is arranged around the base of the stove, as shown, and finallyenters the hole opposite toits starting-point, and commnnicatcs With thechimney, as hereafter specified. In the center of the draft-passage avalve is placed, and so formed that the draft may be directed eitherthrongh the radiatingpipe, arranged around the base, or permitted toascend straight up the chimney. By this arrangement, the full heat ofthe smoke is imparted to the atmosphere by radiation from the pipe keptclose to the floor, which is the true principle of heating. WVhen arapid drait is desired, the valve is turned which opens the directpassage to the chimney. An important featnre in this portion of myinvention is, that it can be applied to any kind of stove. The secondpart of my invention consists in havin g small buttons or knobs on themica lights, r

and having the openings for them so formed that they can be readilysprung into place. The third part of my invention consists in certainimprovements in the grate or lire-pot of the stove, as hercinafterdescribed.

Like letters indicate like parts in each fi gare.

A is the base or table upon which the stove rests; A is the lire-pot. Ais the dome or top of fire-pot. A is the fuel-feeder or rescrvoir. Allthese parts are cast separately and fitted together, as shown.- D is thecircular grate, With fingcrs d, supported by the lngs d on the ash-panchamber E. F is the radiating-pipe; F three-way tirait-passage; Fescape-pipe. a is the skirting or shelf upon which the radiatingpipe Frests. E 18 the ash-pan. 'B is the mica. b s a knob riveted to the mica.12 are vertical ribs, against which the mica fits. These ribs are on theinside of the stove, and are not quite as long as the opening, on eitherside of which thcy are. The space thus left is protected by thehorizontal rib or lip on the outside of the stove top and bottom of themica-space. By this formation it is possible to cast the top or dome ofstove in one piece, leaving the mica-spaces clear without any fitting.It Will thns be seen that the stove can be 1nade very cheaply,consisting essentially of five principal parts, viz., the base or tableA, ash-pan chamber E, firepot A top or dome of stove A, coal reservoiror feeder A each cast separatcly, but formed so as to come togetherwithont mach fitting. The grate D rests on the lngs d, and can be easilyturned aronnd by putting a poker between the fingers d,which act as afence or gnard for holding the coal on the grate while the cinders arebeing removed. In order to prevent the fire-pot getting red-hot, it maybe lined either with tire-brick 0,01 au inner castiron pot might beinserted. F is the threeway draft-passage on the smoke-vent a F is theescape-pipe, and Whieh 1eads down and around the base of the stove, asshown in Fig. 3. The escape-pipe F is closed by the valve G. This valvelies diagonally aoross threeway draft passage 13, separating the tWOparts. and causing the smoke to pass down the pipe F, as indicated byarrow, around the base near the fioor before it can finally escapethrough the pipe F, as also indieated by arrow. By this arrangement, thedraft ean be ohecked and the consumption of fuel correspondinglyredueed, while, by bringing the heated air and smoke around the outsideof the stove, as shown, all the calorie is extracted from it in itspassage through the radiatingpipe F before it escapes.
